David Cameron warns London and UK rioters that their 'faces are known'

Prime Minister David Cameron warns rioters that police will be coming to arrest them.

Addressing the Commons in an emergency debate, the Prime Minister warned those involved in looting and violence over the past few days that they will be dealt with by the law.

He said: "We are making technology work for us, by capturing the images of the perpetrators on CCTV – so even if they haven’t yet been arrested, their faces are known and they will not escape the law."
